mailserver absolute noob question

[Thomas <thomasnawrath@alice-dsl.de>]

Hi there.

I would like to setup a mailserver on my debian machine that can receive 
email from any host and that can be accessed by imap or pop3 (imap would 
be nice). I have seen some howtos on the net but they seemed way too 
complicated. The howtos i saw included spamfilters, anitivr software and 
page after page of config file hacking.

What i am really looking for is a simple mailserver that i can install 
by apt-get something and then configure by a gui/web interface (if 
necessary at all). Then connect to it with my thunderbird and lets go.

So far, exim4 was installed on my sarge by default, although i dont know 
what that means.
If i startup mutt with any user, it says 'no mailbox'.
This didnt ever disturb me, but now i should think of what that means...

Thanks for hints,

Thomas
